I have been lobbying for over 6 years - more like a decade - for somebody to produce a replacement for either the White's Bigfoot, or Tesoro Cleansweep coils. These narrow 18" long coils are superb at scanning large areas for relatively shallow targets, making them excellent for jewelry detecting in large fields, and for vacuuming up recent coin drops. They are so efficient at this that some planted coin hunts prohibit them as an unfair advantage. Also great for beach detecting recent drops, relic/coin hunting huge fields, patch hunting for gold nuggets, even meteorites. See my long thread here for details on the subject.
The short story is that the Bigfoot was a 3" x 18" figure 8 wound coil, specific to some White's models. This design has advantages, but is very hard to make, pretty much a hand made coil. And to really work best, a detector needs to be optimized for it (see additional post below). Barring some process breakthrough, I expected getting this coil back into production to be difficult at best. I therefore also concentrated on the Tesoro Cleansweep design as an option, as it is simply an elongated DD coil, much easier to produce properly in volume at lower cost, and with no oddball operating characteristics.
I tried to get Nokta/Makro in particular to make these, as they are generally open to new ideas, and I thought, and still think, a detector sold with this coil as stock would be a unique offering that would attract attention. That came to naught, unfortunately. Then, about a year ago Detech contacted me on another subject. I used that opportunity to once again bring up the elongated coils as an ignored market, and they seemed enthusiastic about pursuing it. But then nothing, silence for a long time. I pretty much gave up hope. I was contacted by another old detectorist on the subject recently, and said just that. I had lost the original contact info from Detech, and was resigned to these coils never happening again. And frankly, I have one, so I'm covered. I just wanted so much for others to be able to get their hands on these coils, especially for machines that never had them as an option.
Well, miracles happen!! I just was notified that Detech is producing a 4" x 18" DD coil that will be available soon (not sure how soon, but they may chime in on this thread hopefully). I do not know the weight or price, but with Detech I am sure that the price will be reasonable. The best part is that it will be for more than one brand of detector. The list I was just provided with:
- MINELAB'S EXPLORER / E-TRAC / SAFARI
- FISHER'S F75
- TEKNETICS T2, G2, GAMMA / OMEGA
- GARRETT'S ACE AND AT PRO
- WHITES' DFX / MXT / M6
And so without further ado, let me give you your first look at a genuinely new product for some detectors, the Detech Arrow! One of my favorite all-time coils is the Detech Ultimate series, so I know they make some great coils. This is a niche coil, but one many people crave. I want to give a very personal thanks to Detech for doing this, as it is something I have tried hard for a long time to get somebody to do, and they have granted this old guys wish finally. Thank you!
this update is about the 5x10 depth. I was running prk1, 5 recovery and finally found a place that had deep coins. I ended up with a rosey, merc and 5 wheaties. The merc and one wheatie were a solid 9 inches and maybe a little over. I was really happy with the results of the 5x10. I think that's getting right on the edge of max depth for a dime size coin in the soil around here. It was nice finding a place like that to really test out the 5x10. I'm giving it a b+ on depth. Still not as deep as the 11 inch but very respectable.👍

I was talking to Rob yesterday about something I wanted to order from him and the subject of the 10X5 plus the above coil came up. I was just wondering if anyone here has ever used it? He made the statement that he has two of them.
I’m like so many with their money down on the 10X5 and not knowing if are when we’ll get it.

I"m curious if anyone has tried the Coiltek 15" NOX coil and if so their thoughts on it.
This is the coil: https://coiltek.com.au/coils/nox/15-nox-coil/
I used a WOT coil for several years and liked it but ultimately the weight did me in. The coverage area of this new coil intrigues me but I am concerned about the weight.

A lot of you are gonna get the Coiltek 10x5 coil, and some of you are going to be irritated like I am that the Equinox falls over when you set it down.
Went on Amazon and found the cheapest/ lightest rifle bipod I could find:
It would be terrible for a rifle, but it's great for the Equinox. The legs fold out, and while they can get in the way when swinging the detector, I find I'm pretty comfortable using them open. It only weighs about 8 ounces. The best part of it is the clamp, it can be used universally, even on my new carbon fiber shaft. The legs are removable from the clamp block via a thumbscrew.
Another benefit it seems to provide is enough counterweight to relive trigger finger, I've been having a lot of problems with my right ring finger locking up at night. It's a lot better now. The clamp is probably steel, so don't tighten it too much and hit it with WD-40 now and again to keep it from rusting.
